To all whom it may concern .1

Be it known that I, zen of the United States, residing in the city of Portland, county of Multno mah, and State of Oregon, have invented certain new and useful Improvements in Kindling- Blocks, of which the following is a specification.

My invention relates to kindling blocks, to a kindling block shavings, saw dust, ground corncobs, or other combustible and more particularly manufactured from wood matter to give body or bulk thereto, as hereinafter set forth.

Among the salient objects of my inven-v tion are,to provide an improved and economical kindling block which can be readily ignited directly from a match and which will burn with sufiicient intensity to ignite even the hardest coal, thereby doing away with the necessity of using kindling wood, or other fire-starting material; to provide a kindling block with an igniting substance,

producing a self-igniting kindling block, which can be ignited by simply rubbing orscratching the same upon a suitable surface similar to striking a match; to provide in combination with a kindling block of the character referred to, igniting substance which can be ignited only by being struck upon a specially prepared surface, thus providing a safety self-igniting kindling block, which can be shipped with perfect safety.

Other objects and advantages of my invention will be apparent from the following description of one practical embodiment thereof, which I will now describe.

In carrying out my invention, I employ dry wood shavings, sawdust, preferably coarse, or dry coarsely ground corncobs may be used. This is first steeped in turpentine, using approximately 30 parts of the shav ings, or sawdust, to 7 parts of turpentine. I next mix together 5 parts potassium nitrate and 5 parts of charcoal (carbo lign'i) and stir the same into 53 parts of-liquid rosin, which has first been heated to the boiling point, after which the wood shavings, or sawdust, is stirred into the hot mixture until it forms a thick batter-like substance.

This is then poured into suitable by rubbing or striking them against a suitable surf'ace. 'The'fol'lo'wi-ng formula may be used for this purpose:

parts by weight. Potassium chl0rate 4. Gum glue 2. Powdered glass -4E.

A coloring substance may be used such as ultramarine blue, if desired.

This igniting surface is prepared by dissolving the yellow phosphorus in chloroform and heating the same; dissolving the potassium chlorate and gum glue in warm water; then slowly stirring the dissolved yellow phosphorus into the dissolved potassium chlorate and gum glue, and then adding the powdered glass, and coloring matter to give the desired shade thereto. This preparation is then applied to a surface of the kindling block by means of a brush, whereupon the kindling block is made self-igniting by simply striking it upon a suitable surface.

i I will next describe an igniting substance which can be ignited only by striking the same upon a specially prepared surface.

The preparation applied to the kindling block may be made as follows: 1 part of antimony sulfid, 1 part of potassium chlorate, 2parts of glue, 10 parts powdered glass.-

The substance to be applied to the surface on which the block coated with the foregoing preparation may be prepared as follows: 2 parts red glue, 1 part powdered glass. This is dis mixed to the consistency of a batter and applied to the surface on which the block may be struck, for the purpose of igniting the same.

I am aware that many different kinds of igniting compounds can be used, and I do not, therefore, limit my invention to any particular igniting composition.

So far as I am aware, I am the first to phosphorus. 1- part B NJAMIN SAGQRSKY AN-D O'NEPFIFTH TO. WIL IAM .PatentedMay 16,1916. Appl-teation filed'lune 3,1915 seriaimsresa i they can be ignited surface and dropping it into Letters Patent is,-

It will be readily seen that this block has many uses and will be particularly v Welcome for building camp fires and the like.
